    Regional Flood Control District page banner

    The Pima County Regional Flood Control District strives to use forward-looking floodplain management practices to minimize flood and erosion damages for all county residents, property and infrastructure. Regionally, the District is involved in a variety of flood monitoring, flood control and natural resource management activities. We also perform floodplain management activities within unincorporated portions of Pima County.

    We hope you'll take a closer look at the District's many programs and activities. Please contact or visit us if you have any questions, comments or suggestions regarding the District.

    The District Becomes a Class-3 Community, What It Means for Flood Insurance

    On April 1, 2022, the District was upgraded to a Class-3 Community as determined by the Federal Emergency Management Agency. The updated classification rewards Pima County for going above and beyond the federal minimum requirements for floodplain management. The Class-3 rating results in up to a 35% discount of flood insurance premiums for many County property owners. The National Flood Insurance Program has also changed the way flood insurance policies are rated, and is called Risk Rating 2.0.  All new and renewed flood insurance policies will be rated under Risk Rating 2.0. Visit the District's Flood Insurance webpage for more information. 

    Services

    While the District is a regional authority, undertaking flood mitigation efforts throughout Pima County, we do not regulate floodplains within incorporated areas or on Tribal Nations.  For questions related to floodplain permitting within the City of Tucson, Town of Marana, Town of Oro Valley or Town of Sahuarita, please go to the Other Local Floodplain Management Agencies web page for contact information.


    Resources

    Our Resources page contains floodplain permitting resources for the public and licensed professionals, such as a tool to create a property-specific Flood Hazard Map, permit guidelines, construction details, historical aerial photography, and technical tools such as hydrologic and hydraulic modeling software.

    Floodplain Resources for Real Estate Professionals

    The Pima County Regional Flood Control District (District) wants to help you understand the potential pitfalls of buying or selling properties that are in the floodplain and protect your clients in the process. The District has created a dedicated website for real estate professionals filled with resources on floodplains, insurance, safety, and more.

    Rules, Ordinance, Policies & Procedures

    (Directory of Documents)

    The District derives its regulatory authority from Title 16 of the Pima County Code, otherwise known as the Floodplain Management Ordinance (Ordinance).  The Ordinance is augmented by policies and procedures that serve to clarify the requirements of the Ordinance, standardize implementation of the Ordinance, establish construction guidelines and provide tools for staff and the public to enhance the permitting process.

    The Ordinance, Policies & Procedures and other regulatory documents can be found on the Rules and Procedures page.

    Public Outreach

    Our Public Outreach page contains brochures, FAQs, flood disaster information, flood videos and Sheriff Hank Highwater's Flood Safety Fun Page for Kids.

    District Brown Bag Series

    The District hosts a monthly brown bag series on a variety of topics, and features experts in the topic field. Certified Floodplain Managers are eligible to receive 1 continuing education credit per presentation.

    Projects and Reports

    Projects

    The District has a long history of constructing improvements to enhance flood safety and community well-being in Pima County.  Our Projects page contains links to in-depth information about completed and ongoing projects initiated by the District.

    Reports

    Our Reports page contains reports spanning the entire spectrum of District activities, including floodplain special studies, Technical Data Notebooks, and environmental evaluation and restoration reports, as well as quarterly and annual reports of District activities.

    Historical Floods

    We are often asked, "When was the last flood on my property?"  While we don't often have flood information specific to individual parcels, and past flood events aren't necessarily indicative of the timing or severity of future flood events, looking at past flood events can be very instructive.  To that end, we have created a web page dedicated to historical flood events in Pima County.
